Incorporating Cemfree allowed a carbon saving of up to 84%, when compared to a block using PC
Jacksons Environment Manager Steve Livingstone and Supply Chain Manager Andy Lusher broke down the constituents of their Canewdon block to evaluate where they could make significant carbon savings.
They found that they could use Cemfree to replace the Portland cement (PC) in the concrete mix. To demonstrate that this was possible, a number of Cemfree modified Canewdon blocks were cast as part of the DULCET programme that Jackson and Cemfree are both members. These blocks were used alongside the hundreds of Canewdon blocks that made the new revetments. Incorporating Cemfree allowed a carbon saving of up to 84%, when compared to a block using PC.
Other carbon saving methods were also used. Basalt Rebar, and alternative to steel rebar was also used, as well as a carbon negative aggregate. With the project using Cemfree, Basalt rebar and Steel rebar combined, a total of 88% carbon was saved per block.
For their efforts in quantifiably reducing their carbon emissions, Jackson Civil Engineering was named a Carbon Champion by the Institution of Civil Engineers (ICE).
